PROBLEM TO BE SOLVED: To determine whether a power storage stack is replaced, while suppressing an increase in a memory storage space.SOLUTION: A controller performs: obtaining voltage information of each power storage stack and storing the voltage information in memory when an ignition switch is turned off from on; and obtaining voltage information of each power storage stack when the ignition switch is turned on from off, and, if the voltage information is different from the one stored in the memory, determining that a power storage stack represented by the voltage information is replaced. The voltage information is an average value of voltage values in all power storage elements contained in the power storage stack, or a voltage profile that is constituted by a bit specifying a relationship in magnitude of voltage values on two power storage elements, and represents a relationship in magnitude of the voltage values on all power storage elements contained in the power storage stack. |
